Fetch metadata, ownership, and links for a specific Google Drive file.
AI agents call get-file-metadata to retrieve information from Universal Mcp Toolkit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata information (ownership, links) about a Google Drive file, which is a read-only operation with no side effects. It does not create, modify, delete, or execute any operations. The blast radius is minimal since it only exposes file metadata that the authenticated user already has access to.
From the tool's definition Tool name 'get-file-metadata' and description 'Fetch metadata, ownership, and links for a specific Google Drive file' indicate data retrieval without modification or deletion.
Attacks that exploit this kind of access
Fetch metadata, ownership, and links for a specific Google Drive file. It is categorised as a Read tool in the Universal Mcp Toolkit MCP Server, which means it retrieves data without modifying state.
Register the Universal Mcp Toolkit MCP server in PolicyLayer and add a rule for get-file-metadata: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Universal Mcp Toolkit. Nothing to install.
get-file-metadata is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get-file-metadata rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get-file-metadata. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get-file-metadata is provided by the Universal Mcp Toolkit MCP server (markgatcha/universal-mcp-toolkit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
